IMPROVED MACHINE FOR PUNCHING RAILROAD RAILS.

Specification forming part of Letters Patent No. 38,509, dated May 12, 1863.

To all whom it may-concern:

Be it known that we, ALFRED SowER and MARTIN PAYNE, both of Troy, in the county of Rensselaer and State of New York, have invented a new and Improved Machine for Punching Railroad-Rails and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which-- 7 Figure 1 is a longitudinal vertical section of our invention, taken in the line x m, Fig. 2; Fig. 2, a transverse vertical section of the same, taken in the line y 9 Fig. 1; Fig. 3, a face view of a rail punched at one end.

Similar letters of reference indicate corre sponding parts in the several figures.

This invention relates to a new and improved machine for punching railroad-rails directly after being rolled and while in a heated state.

The invention consists in the employment or use of rising'and-falling blocks provided with suitable punches and operated through the medium of eccentrics and rollers, the blocks being provided with two punches each, so as to punch both sides of the rails at one operation, and the rails being placed on rollers which are turned simultaneously by means of belts or their equivalents, all being arranged in such a manner that the rails may be punched expeditiously at both ends and with less labor than the work can now be done.

To enable those skilled in the art to fully understand, construct, and use our invention, we will proceed to describe it.

A represents a horizontal bed or bar, which is supported at a suitable height by uprights B B G C are two heads placed one at each end of the bed or bar A, and having a lever, D, fitted in the upper end of each on fulcrumpins a. Each head 0 is provided with two lips or guides, b b, one at each side, between which blocks E are placed and allowed to work freely up and down. In the upper part of each block E there is placed transverely a pin, 0, and these pins pass through curved slots 01, which are made in the levers D eccentrically with the fulcrum-pins a, as shown in Fig. 1. The lower edges of the levers D, at

their inner parts, are also of curved form, ax shown at a, said parts 0 being concentric with the slots 0?, and consequently eccentric with the fulcrum-pins a of the levers D. The curved parts 0 of the levers bear on frictionrollers F, which are placed in the blocks E.

In the lower end of each block E there are fitted two punches, ff, one at each side, as shown in Fig. 2. The space between the two punches in each block is sufficiently wide to admit of the upper part of the rail passing between them, so that when the punches are forced down they will cut or notch the edges of the base of the rail at each side.

F represents a rail, which is placed upon rollers G in the bed or bar A. The rollers G are provided with flanges at their ends, to retain the rail'in proper position, and said rollers are placed on shafts H, which project at one end through one side of the bed or bar A, and have pulleys g on them, around which belts it pass, one of which passes around a pulley, 'i, on a shaft, j, said shaft having a fly- Wheel, I, upon it.

The operation is as follows: The rail, after being rolled and cut of proper length, is placed on the rollers G, and is moved longitudinally by turning the rollers Gr through the medium of the belts h, or their equivalents, so that one end of the rail will pass between the punches f f of one of the blocks E, the latter being then forced down by raising the outer end of its lever D, the curved part c of said lever acting upon the friction-roller F in the block. When the rail is thus punched at one end, as shown at a in Fig. 3, the block which performed the work is raised by forcing down the outer end of its lever D, the pin 0 and curved slot (1 causing the block to rise. The rail F is then moved in an opposite direction by turning the rollers G in a reverse direction, so that its opposite end will pass between the punches f f of the other block, which is forced down, and its punches made to act upon the rail in the same way as the punches first described. Thus it will be seen that the rail may be punched at both ends very expeditiously, and punched simultaneously at both sides.

We would remark that the punches ff pass into suitable bolsters, J, in the bed or bar A.

This invention has been practically tested punches f attached, all arranged for joint 0pand found to effect a great saving in time and eration, as and for the purpose herein set labor. forth.

Having thus described our invention, what ALFRED SOWER. We claim as new, and desire to secure by Let- MARTIN PAYNE. ters Patent, is-. Witnesses:

The rollers G in the bed or bar A, in con- F. J. PARMENTER,
